RADIATOR CAP.

Application filed November 15, 1922. Serial No. 601,118..

To al] whom it may concern.'

Be it known that we, TILLMON H.` PEAR- son and GEORGE BINFORD BAYBURN,citizens of' the United States, residing at Waco, in the county ofMcLennan and State of Texas, have invented certain new and usefulimprovements in Radiator Caps, of which the following is aspecification.

This invention relates to caps, designed primarily for use in connectionwith radiators for motor vehicles, but it is to be understood that a capin accordance with this invention, can be employed for any purposeswherein it is found applicable, and the invention has for its object, toprovide, in a manner as hereinafter set forth, a cap for radiatorsformed with means whereby the cap is permanently secured to the radiatorand further having means to enable the quick and ready filling of theradiator when occasion so requires, without the removal of the cap,under such conditions preventing the displacement or accidental losingof the cap, to be equally applicable for use for protection ofmotormeters.

Further objects of the invention are to provide a radiator capwhich issimple in construction and arrangement, strong, durable, efficient vinit-s use, conveniently operated, readily set up with respect to theradiator, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1 is a front elevation, brokenaway, of a radiator of a motor vehicle, showing the adaptation therewithof a cap in accordance with this invention,

F ig. 2 is a sectional plan with the cap open to permit of the fillingof the radiator,

Fig. 3 is a view similar to Fig. 2, with the cap closed,

Fig. 4 is a section on line 4-4 of Fig. 2.

Referring to the drawings in detail, 1 denotes a radiator, formed with afilling opening 2.

Secured to the top of the radiator 1 and surrounding the filling opening2, is a closure cap, in accordance with this invention, for the saidfilling opening 2, and said cap comprises a cylindrical neck 3, formed:it its lower end with a lateral flange 4, which is secured in anysuitable manner to the radiator 1. The neck 3, or which may he termed afilling tube, is offset as at 5, to provide-a shoulder 6 intermediatethe ends thereof.. The offset portion 5 of the neck, is formed at theouter end thereof, and which terminatesin an integral top piece 7, upsetas at 8 to provide a stop. The top piece 7 is furthermore provided withan entrance opening 9 for the neck or tube 3. Associated with the neckor tube 3, as well as being shiftably connected therewith, is a closurecap 10, formed with a depending annular flange 11, which is inset as at12, to provide a shoulder 13, the latter bearing against the shoulder 6.The insetting of the flange 12, in connection with the shoul ders G and13, provides means for permanently connecting the closure to the neck ortube. The closure 10 is formed with an opening 14, adapted when theclosure 10 is shifted, to register with the opening 9, so that theradiator 1 can be filled when occasion so requires. The closure 10 isfurthermore provided with an arcuate guide 15, into which extends thestop 8, whereby the shifting movement of the closure 10 is limited ineither direction, due to the fact that the l stop 8 contacting witheither of the end walls of the guide 15 arrests the shifting movement ofthe closure 10.

Formed integral with the closure 10, is a vertically disposed thumb orfinger piece employed for the shifting of the closure 10 when occasionrequires, and said thumb or finger piece consists of a T-shaped rodl,havilng a fiat disk 17, formed integral therew1t The normal position ofthe closure is as shown in Figure 3, and when in such position, theopening 14 is arranged at a point of two hundred seventy degrees withrespect to the circumference of the closure. The normal position of theopening 9 is at one hundred eighty degrees with respect to thecircumference of the neck or tube 3,

whereby when the closure is in normal position, the opening 9 is closed,but when it is desired to fill the radiator, the closure is shifteduntil the opening 14 registers with the opening 9 and when sopositioned, the radiator is filled.

The closure is permanently connected to the neck or tube 3, and by thisarrangement, there is no possibility of the closure being accidentlymisplaced or lost.

From the foregoing description taken in connection with the accompanyingdrawings, the radiator cap is set up which is permanently connected withthe radiator, and which can be conveniently operated, so that theradiator can be filled when occasion so requires, and although thedrawings illustrate the preferred embodiment of the invention, yet it isto be understood that changes'in the details of the construction can behad without departing from the spirit of the invention as claimed.

Vhat is claimed is l. A device for the purpose set forth comprising ahollow cylindrical neck having its outer portion of greater diameterthan its remaining portion thereby providing a flat right angularlydisposed peripheral shoulder intermediate' the ends thereof, said neckVY ranged shoulder abutting against the shoulder of the neck forpermanently connecting the cap and neck together, said cap having acircular opening adapted to register with the opening in said top andfurther provided with an arcuate guide into which extends said stop,said guide being of a length Y to obtain a complete quarter turn of thecap with respect to said top, and an upstanding actuating meansconnected to said cap centrallythereof, said stop and guide limiting theshifting movement of the cap.

2. A device for the purpose set forth comprising ahollow cylindricalneck having its outer portion of greater diameter than its remainingportion thereby providing a dat rightangularly disposed peripheralshoulder intermediate the ends thereof,'said neck provided with anintegral top formed with a circular opening and further upset to form astop, said opening and stop being diametrically opposed, a shiftableclosure cap including a depending annular iange having the inner portionthereof inset to provide a flat right angularly disposed inwardlyarranged shoulder abutting against the shoulder of the neck forpermanently connecting the cap and neck together, said cap having acircular opening adapted to register with the opening in said top andfurther provided with an arcuate guide into which extends said stop,said guide being of a length to obtain a complete quarter turn of thecap with respect to said top, an upstanding actuating means connected tosaid cap centrally thereof, said stop and guide limiting the shiftingmovement of the cap, and said guide formed from an upset portion of saidcap and having one end thereof disposed diametrically with respect tothe opening in the cap.

3. A device for the purpose set forth? comprising a hollow cylindricalneck having an expanded outer portion thereby pro,- viding a flat rightangularly disposed peripheral shoulder intermediate the ends of theneck, said neck further having the top formed with an opening andfurther formed with an upset integral polygonal portion providing astop, a shiftable closure cap mounted on the neck and formed with aflange having a contracted inner portion overlapping the fiat shoulderof the neck whereby the latter and the cap are permanently connectedtogether, said cap formed with an opening and further formed with anintegral upset portion providing an arcuate guide of a length to obtaina complete quarter turn of the cap with respect to said top and intowhich extends said stop, said guide having a closed top and ends, saidguide and stop limiting the shifting movement of the cap, and upstandingmeans centrally of and formed integral with t-he cap to provide anactuating element for the closure.

In testimony whereof, we aIiX our signatures hereto.
